STEM EXPOSITION WORKSHOP #2January 7, 2013

Check in with participants

• How's it going?• Any issues we can help with?• How many students are you working with?

Science:Hypothesis & ProcedureQuick review about key pieces

Science Hypothesis• If __________, then ____________.

Science: Procedures• Materials list

• Step by step so others may duplicate exactly• detailed amounts• how variables will be measured

• Repeat trials for multiple conditions!!!• at least 3• multiple subjects (i.e. plants, people interviewed)• multiple tests (i.e. rolling object down a ramp many times

Engineering: Criteria & Prototype Design

Engineering: design criteria• Types of design requirement/criteria for general products

• Materials list - same as science

• Preliminary design & prototypes• Sketches, drawings and models• Use readily available materials: cardboard, paper, foam-core, found

objects• Construction kits such as lego, meccano, fishertechnik, electric

circuit boards

COLLECTING DATAScience & Engineering

What Kind of Data Do Scientist/Engineers Use?• Determine how researchers in your field of study interpret

their data.

• Take note of any mathematical formulas or equations that will be needed to describe the results of the experiment

• Take note of any information that will be needed to build a prototype.

Take Notes Each Day of the Project• Observations

• Potential problems

Take Pictures• Observational data

• Reminders of events

• Use for display boards

• Must be in focus & understandable by anyone!

Numerical Data

Science• controlled variables

• independent (manipulated) variable

• dependent (responding) variable

Engineering• design criteria

• prototype

• rebuild

Monitor & Adjust …If When Something Goes Wrong• Most experiments/ designs do go "wrong”.

• Keep a complete record in notebook!

ANALYZING DATAScience & Engineering

Questions to Ask When Looking at Data• Did I collect enough data?

• Is the data accurate?

• Did my results match my hypothesis?If, yes...

• How does the data supports this conclusion?

If no… • How does the data support this conclusion?

Graphs• Used to show how the hypothesis was answered / design

met the criteria for improvement

• Most controlled investigations will be a XY Scatter

• At least one for all projects!

• Resource: Create a Graph from Kid Zone (NCES)

Formulating Conclusions• Sample Science Conclusion outline

• Follow the Project checklists

Writing the research paper• What should be included – final report check list

• Template/chart of research paper format

• Abstract – for students moving on to other fairs

Example Projects

Invention

• Quiet Down
